ABSTRACT:
Component3is pressed onto a circuit board4so that their respective metal interconnects5, 6are in close contact with each other, and ultrasonic vibration is applied to the suction nozzle14holding the component3. Friction is thereby generated between metal interconnects5, 6whereby the component3is bonded on circuit substrate. Suction nozzle14for handling components is made of stainless steel and has a working face14aprovided with a hardened layer14b, or alternatively, suction nozzle14may have a suction head14chaving a working face14amade of cemented carbide. Working face14aof suction nozzle14is refined by polishing as required during the mounting operation.
